"I still love my wife but I can't live with her cheating, lying, replacing me and then running back to me."
You can love someone and be unable to live with them. Your wife has an established pattern of behavior, and seems, at this time, unwilling to change. You've stated you're unwilling to live with her while she maintains that pattern. But as long as you stay with her, you're tolerating that behavior, and in some ways sanctioning it.
Her problems, whatever they may be, are ultimately her own. This isn't something YOU can fix or change; your personal experience has taught you that. It's time to break the pattern.
